SPECIFICATION forming part of Letters Patent No. 396,917, dated January29, 1889.

Application filed August 1 0 1888. Serial No. 282,437- (No model.)

To all whom it may concern.-

Be it known that I, CHARLES BUTCHER, a citizen of the United States, andaresident of Cambridge, in the county of llliddle. x. and State ofMassachusetts, have invented new and useful Improvements in InlaidFloors or \Vood Coverings, of which the followin g, taken in connectionwith the aceom ntnying drawings, is a specifit'iation.

This invention relates to improvements in floors and ceilings, as wellaswainscotings or panelings; and it has t'or its object the production ofan inlaid tloor or surface at a very reduced cost and simplicity ofmanufacture, as will hereinafter be more fully shown and described,reference being had to the accompanying drawings, whereiu- Figure 1represents aplan view of the invention. liig. 2 represents across-section on the line A l shown in Fig. l; and l ig. 3 represents aside elevation of one of the inlaid boards.

Si in ilar letters refer to similar parts wherever they occur on thedilterent parts of the drawlugs.

In making my improved floor, ceiling, &c., I take boards (I u ofsuitable length and width, in the top of which I malt e lateral recessesd o, right-angled, cnrved, or diagonal, according to the pattern to beproduciul, and in said recesses are inserted and glued the blocks 1) I)I), having the grain preferably crossing that ol the grain of the boardsac, as shown. In the sides of theboards a a, Intake longitudinal grooves(1" a, one in each side of said boards, which groovespass alternatelythrough the board (1 and its inserted blocks Z; l), as shown intlntdrawings. In said grooves are inserted the thin metal tongues e e,which serve .not only to hold the sides oi theboards u (1 together, soasto present one from rising or falling below the other in the series,but said metal tongues also serve for the purpose of holding permanentlythe blocks 1) I.) in position relative to the boards a u, as shown. Themetal tongues c c are provided with elongated slots or perforations c c,through which are driven in a slanting direction the fastening-nails (Z(I, said nails passing through the lower portion of the boards (L a andthe lateral inlaid blocks?) 11, as shown,their points being driven intothe lower floor or joiste below, as shown in Fig.

It is'essential that the side grooves, a a", should pass alternatelythrough the edges of the main boards a. a and the lateral inlaid blocksZ Z), so as to cause the metal tongues c c to rest: alternately ingrooves in such boards and its 1 atcral blocks or inlaid pieces b I),for the purpose ot holding such respective parts together, and thuspreventing the upper surfaces of said blocks from warping or risiu aboveor below the upper surfaces of the boards a a, and thus preserving andmaintaining a uniform and even upper surface of the floor or woodcovering.

In Fig. lv oi the drawings I have shown a checker-board pattern producedby my im proved floor or wood covering; but this is not essential, asany other desirable pattern may be produced, accorrjling to the shapesor sizes of the blocks 1) 1) relative to the boards a a, withoutdeparting from the essence of my invention. The door or wood coveringthus produced has every appearance of a costly inlaid tloor, in whichthe component parts are firmly united and held together so as to preventany warping or irregularity of surface whatsoever.

\Vhat I wish to secure by Letters Patent and claim is The improved tlooror wood covering, as described, consisting of the boards a a, havinglateral or equivalent recesses ct a, and the blocks 7) I), inserted insaid recesses, in combination with the metal tongues c c and grooves aa" in the sides of said boards, said grooves passing alternately throughthe edges of the boards and the blocks 1) Z), substantially as and forthe purpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this l3tl'i day of April, A.l). 18%.
